Question

Find the area of a rhombus whose side is 8 cm and whose altitude is 5cm. If one of its diagonal is 10 cm long, find the length of the other diagonal.​

Answer 1

Answer:

area of rhombus = 8×8

=64 cm^2

area of rhombus = 1/2 × diagonal1× diagonal2

64=1/2×10×diagonal2

diagonal2 = 64/5

diagonal2= 12.8cm
